ADJUSTABLE HOOD HINGE AND BRACE ROD.

Application filed December 6, 19-24.

My invention relates to hood structures for enclosing the engines ofmotor driven vehicles; and the object thereof is to provide an improvedadjustable hinge and brace rod device for connecting the upper ends ofthe radiator and cowl at the front end of the body of the vehicletogether, which rod and the parts and features associated therewith inaddition serve to provide a pivotal or hinge support for the upper endsof the doors commonly present in vehicle hoods.

The drawing accompanying and forming a part of this specificationillustrates what I now regard as the best form of my invention; althoughthe same may be variously modified, and is regarded as including allsuch variations and modifications of the particular form shown as comewithin the scope of the concluding claims, wherein the distinguishingfeatues in which my invention consists are particularly pointed out.

In the drawing:

Figure 1 is a fragmentary view, mostly in side elevation, showing theupper ends of the radiator structure and the cowl of a motor drivenvehicle connected together by a hood hinge and brace rod device made inaccordance with my invention.

Figure 2 is a similar View showing the parts in plan.

Figures 3 and t are side and plan views upon a larger scale than Figures1 and 2 showing the hinge and brace rod element by itselfpand apart fromthe radiator, the cowl and the doors of the hood.

Referring to the drawing, the reference numeral 5 designates the cowl orfront end of the body of a motor driven vehicle, and 6 the radiatorstructure whereby the water employed for cooling the engine of thevehicle is cooled. The exterior casing only of the radiator is shown asthe water cooling elements and features thereof form no part of thispresent invention, and may be of any suitable form.

The ends of the cowl and radiator casing are suitably shaped to providejamb or abutment portions 7 and 8 upon which the rear and front edges ofthe hood doors 9, 10 rest when the doors are closed, at which time theyprovide a housing enclosing the engine which drives the vehicle as willbe understood.

Extending between the upper ends of the radiator and cowl is a combinedbrace and Serial No. 754,360.

hinge rod 11 which forms a pivot for the hinges 12 at the upper ends ofthe doors 9, 10 as is usual in hood door constructions. The two ends ofsaid rod are connected, respectively, to the radiator structure and tothe cowl; and said rod as will be observed constitutes the onlyconnection between the upper ends of said parts and serves as a braceand tie rod which maintains them the proper distance apart or, asotherwise expressed, holds the radiator structure in its proper uprightposition as the cowl (being a part of the body) is the more immobile ofthe two members connected by the rod.

The front end of the rod 11 is bent down at 13, and provided with a holeat 14s to receive a cottor pin; said hooked end being adapted to passthrough a hole in the jamb or flange 8 of the radiator casing when therod is in use.

The rear end of the brace and hinge rod 11 is threaded at 15, and screwsmore or less into a threaded extension or neck 16 of a connecting member17 whereby and through which the said rear end is fastened to the cowl5. ed with a hole 1.8 at right angles to the neck 16, and the same isshown as fastened to the Said connecting member is providjamb portion 7of the cowl by a bolt 19, the

nut of which is indicated by the numerical 20. A collar 21 is shown asarranged so that the hook 13 extends therethrough; and both the collarand the nut 20 are preferably fastened (as by welding) to the jambs 7and 8, in order to secure large areas as the joints between the ends ofthe rod and the cowl and radiator and prevent the sharp edges of thesheet metal from which said members are made from cutting the part 13and the bolt Obviously the position of the connecting member 17 and hook13 may be reversed, as it is immaterial which end of the rod is fastenedto the radiator casing and which to the cowl.

In making use of my improved adjustable connector and hinge roe devicethe hook shaped end 13 is connected with the flange or jamb 8 ashereinbefore explained, and the connecting member 17 screwed to agreater or less extent upon the threaded end 15 of the rod 11; the doorsbeing in place. during such adjustment of the parts and the rear end ofthe rod being lifted slightly when the connecting member is to bescrewed on or off the rod as will be understood. By such a number ofrepeated trials as may be necessary a position of the connecting membern12 he found such the the radiator structure will be properly positionedrelative to the fun and other parts of the engine not shown, and suchthut the front and rear ends of the doors will'rest noperhx upon thejznnhs "1' and 8 with the hole 18 in alignment with the nut 90 and withthe hole in the juinh T through which the bolt 19 in to 1721595:whereupon the conneetintg nieinhe and rear end of the rod ll :1 refastened to the cowl structure by putting the bolt 15) in place ts willbe undcretoeni.
